Data Handling and Visualization

Types of Plots

• Distributions
  • Histograms, density plots, box plots, pie charts
• Bivariate
  • Line plots, scatter plots (with regression lines and with transparency), hexbin plots
• 3D
  • 3D plots, contour plots

Extras

• Control linestyle, linewidth, point style, point size, titles, axis labels, axis ticks, font sizes

• Annotations

• Subplots

• Interactive plots saved as html

• Ask Julius to get the history of 3-month, 1-year, 5-year, and 10-year Treasury yields from FRED.

Visualization Examples

• Ask Julius to create a density plot of marketcap in the metrics dataset.
• Ask Julius to save as a jpeg and provide a link.

• Ask Julius to create a bar chart of total marketcap by sector using the merged dataset.
• Ask Julius to make the font size larger.
• Ask Julius to create a pie chart of the number of firms by sector using the merged dataset.

• Ask Julius to use seaborn to create a boxplot of marketcap by sector. Ask Julius to save as a png.
• Ask Julius to use plotly to create a boxplot of marketcap by sector in the merged dataset and to include the ticker in the hover data. Ask Julius to save as html.

• Ask Julius to calculate the daily percent changes in the crude oil price and to create a filled density plot using seaborn.
• Ask Julius to create a filled contour plot of the function \(z=(4x + y)^2\) for \(x\) and \(y\) between \(-2\) and \(2\).
• Ask Julius to create a 3D plot of the same function on the same range.

• Ask Julius to use plotly to create a figure containing line plots of the 3-month, 1-year, 5-year, and 10-year Treasury yields. Ask Julius to save as html.
• Ask Julius to recreate the figure using the plotly_white template.
• Ask Julius to use plotly to create an animation showing a plot of the 3-month, 1-year, 5-year, and 10-year Treasury yields as a function of maturity. Tell Julius to use the date as the animation frame.
